KILN FOR BURNING BRICK, TILES, 80G.

SPECIFICATION forming part of Letters Patent No. 288,466, dated November 13, 1883.

Application filed May 24,1883. (No model.)

f aZZ whom it may concern:

Be it known that I, HENRY MoGUn, of St. Louisband State of Missouri, have invented a new and useful Improvement in Kilns for Burning Bricks, Tile, and other Wares, of which the following is a full, clear. and exact description.

The object of the invention is to improve brick kilns, as hereinafter described and claimed.

Referenceis to be made to theaccompanying drawings, forming part of this specification, in which similar letters of reference indicate cor-. responding parts in all the figures.

Figure 1 is a horizontal section of my improved kiln. Fig. 2 is a vertical section on line w a: of Fig. 1. Fig. 3 is a front elevation of the kiln and transverse section through the furnaces on line 3/ y, Fig. 2. Fig. 4 is an end elevation of one of the furnaces, and Fig. 5 an end elevation of the kiln.

I propose to arrange aseries of furnaces, a, on the opposite sides of the kiln, with flues b from the back ends passing through the side walls into the kiln, which are arranged to distribute the heat at equal distances apart along the whole length of the sides and into each of the spaces. 0, equally and alike between the benches d, for more equal effect on the articles spaces d in the arch, with inlet-openings e at the front for the admission of air,and passages f from said spaces into the furnace, whereby the air will descend upon the fire-bed in a manner to effect better combustion by the supply of fresh air to the gases rising from the coal. I also propose to arrange perforated pipes 9 along the inside of the furnace-walls, with the ends opening at the front and the sides to the air for the supply of air to facilitate the combustion of the gases, and to prevent the forming of clinkers on the side walls of the furnaces.

For preventing the forming of clinkers on the grates, I propose to have water-pans h in the ash-pits,to be supplied by pipes t from any tank j, to be regulated by valves is.

Back of the fire-grate I propose to have a dead-wall, Z, whereon the fuel may be banked up to close passages b, and prevent the cold air from rushing. into the kiln at any time when the fire may have to be stopped for replacing grate or bearing bars that may fall down. V

\Vith these improvements Ihave a more efficient and economical kiln than others now in use, and especially one that is calculated to burn more evenly,and consequently better.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- 1. A brick-kiln furnace having in its arch the'hollow spaces d and air-inlets cf, whereby the air will descend upon the fire-bed, as described.

2. The combination, with a kiln-furnace, of the perforated air-pipes 9, arranged along the inside of the walls, whereby a more perfect combustion will take place and the formation of clinkers be prevented, as set forth.

HENRY MOOUE.
